I'm about to set up a web-page where my SSRS will be viewed. I see that there are three options(Report Server Web service, ReportViewer controls for Visual Studio, and URL access)
I wanted to know about the main difference between "ReportViewer controls for Visual Studio" and "URL access" - does the "ReportViewer controls for Visual Studio" require the end user to have extra plug-ins? Thanks!
ReportViewer needs to make calls to the SSRS Server via SOAP requests I believe. It is basically a window into the SSRS site and has all the functionality in the services available visually at once. The viewer usually presents the report in a format like:
http:// (server)/Reports/Pages/Report.aspx?ItemPath=%2f(ReportName)
The URL access is generally the webservice of SSRS doing the work for you directly with commands given to it directly. It is important to note that I believe the web service does all the work for both but the site access also has visual studio on the host and client location also doing some after market CSS rendering and other things from their default locations. The Webservice is just rendering the report and potentially the header where the parameters are. You can even pass in parameters in the URL if you know what you are doing with SSRS. However this does not present a usable object for rendering except in a browser.
EG: say I have a report that takes two parameters: A 'Start' datetime and an 'End' datetime. I can call the web service and render the report and input the parameters at the same time. I could host this in my own browser viewer, but not really do much with the object without developing something else to consume it.
http:// (server)/ReportServer/Pages/ReportViewer.aspx?%2f(ReportName)&rs:Command=Render&Start=11/01/2012&End=1/1/2013
You can also do your own calls in .NET with talking to the SSRS web services or creating your own proxy classes. This is for applications when you want to render in custom formats with events triggered from potentially an application that is not on a set schedule or you want to decouple from the SSRS site and maintain your own settings without relying on the server being the decider of when things happen.
We have a SSRS report server 2008 (not R2) on our internal network that has reports (and data) we want users on the Internet to be able to run. We've created a vb.net web application that users will log into and run reports from. The application runs in our DMZ and is connected to the SQL Server database (running on the same server as the SSRS) via an open port.
I suspect we have to use SSRS Web Service to access the reports since url access would require opening up the SQL Reporting Server to the outside (we don't want to do this). Correct?
I've created a page in the Web application that can render a SSRS report to file but I want to display the report to the user on a web page (and still provide ability to save report). What do I need to do? Can I have the resuls of the Render command be displayed in the Report Viewer or some other control?
Pointers to examples would be great.
Thanks
You're looking for the ReportViewer Controls, specifically the Web version (there's also a WinForms version):
If you incorporate that into your web application you will get a control you can place on any page;
The control can connect to your SQL backend from the web server, so you don't have to expose your SQL backend to anyone else;
The control by default renders in the browser (utilizing the html renderer) providing the user with a nice preview.
The control comes with a nice toolbar that allows for navigating, searching, printing, and also exporting (i.e. saving) to various formats.
Check out the download link for Microsoft Report Viewer 2010 Redistributable Package, which contains both the Web and WinForms controls.
PS. Opening up the SSRS Web Service directly to the world is not something you'd typically want to do. The web service is great for secure communication with your own applications, and gives you some more fine-grained control (as you've noted, by creating a page to export/render reports). For providing a site with reports however, I'd recommend the ReportViewer.
I have an Access db file, and I need to slice and dice the data for various reports that my boss wants.
Is Microsoft Reporting Services a tool that is appropriate for this kind of activity?
If so, would I import the Access data in SQL Server, then the reporting services is a tool that works on SQL Server, allowing the report builder to build custom reports?
SSRS is great for what your trying to do if you wish to stick with Micrsoft tech.
SQL Server Express Adv edition comes with report server. There are plenty of guides out there for install / set up but once going you can use a little application called Report Builder that lets you design the layout of the reports themselves.
Reporting server esentially generates reports from templates you produce in report builder app.
The free edition of report server that comees with SQL Express Adv can export reports into three types, word files, excell or PDFs and does a very good job at it. It also exposes a webservice with a whole myrad of web methods thats very very usefull. ASP.Net also has a control which you can drop into your apps which will render a report.
So in short, yes :)
Hope this helps.
I have been studying SSRS 2005 / 2008 in the past weeks and have created some server side reports. For some application, a colleague suggested that I look into RDLC for that particular situation. I am now trying to get my head around the main difference between RDL and RDLC.
Searching for this information yields fragmented information at best. I have learned that:
RDLC reports do not store information about how to get data.
RDLC reports can be executed directly by the ReportViewer control.
But I still don't fully understand the relation between the RDLC file and the other related systems (the Reporting Server, the source database, the client).
In order to get a good grasp on RDLC files, I would like to know how their use differs from RDL files and in what situation one would choose RDLC over RDL. Links to resources are also welcome.
Update:
A thread on the ASP.NET forums discusses this same issue. From it, I have gained some better understanding on the issue.
A feature of RDLC is that it can be run completely client-side in the ReportViewer control.
This removes the need for a Reporting Services instance, and even removes the need for any database connection whatsoever, but:
It adds the requirement that the data that is needed in the report has to be provided manually.
Whether this is an advantage or a disadvantage depends on the particular application.
In my application, an instance of Reporting Services is available anyway and the required data for the reports can easily be pulled from a database. Is there any reason left for me to consider RDLC, or should I simply stick with RDL?
From my experience there are few things to think about both things:
I. RDL reports are HOSTED reports generally. This means you need to implement SSRS Server. They are a built in extension of Visual Studio from SQL Server for the reporting language. When you install SSRS you should have an add on called 'Business Intelligence Development Studio' which is much easier to work with the reports than without it.

Benefits of RDL reports:
You can host the reports in an environment that has services running for you on them.
You can configure security on an item or inheriting level to handle security as a standalone concept
You can configure the service to send out emails(provided you have an SMTP server you have access to) and save files on schedules
You have a database generally called 'ReportServer' you can query for info on the reports once published.
You can access these reports still through 'ReportViewer' in a client application written in ASP.NET, WPF (with a winform control bleh!), or Winforms in .NET using 'ProcessingMode.Remote'.
You can set parameters a user can see and use to gain more flexibility.
You can configure parts of a report to be used for connection strings as 'Data Sources' as well as a sql query, xml, or other datasets as a 'Dataset'. These parts and others can be stored and configured to cache data on a regular basis.
You can write .NET proxy classes of the services http:// /ReportServer/ReportingService2010 or /ReportExecution2005. You can then make up your OWN methods in .NET for emailing, saving, or manipulating SSRS data from the service directly of a Server hosting SSRS reports in code.
Programmatically Export SSRS report from sharepoint using ReportService2010.asmx
Downsides:
SSRS is kind of wonkey compared to other things on getting it up fast. Most people get confused by the security policy and designing reports as an 'add on' to VS. SQL 2005 = VS BIDS 2005 , SQL 2008 = VS BIDS 2008, SQL 2012 = VS BIDS 2010(LOL).
Continuing on 1 the policy for security settings IMHO are idiotically overcomplex. There is server security, database security and roles, two security settings on the page hosted for the service. Most people only set up an admin than can't get in and wonder why other users cannot. Most common complaint or question on SSRS is related to getting in generally from my experience.
You can use 'expressions' that will supposeduly 'enhance' your report. Often times you do more than a few and your report goes to a crawl in performance.
You have a set amount of things you can do and export to. SSRS has no hover over reporting I know of without a javascript hack.
Speed and performance can take a hit as the stupid SSRS config recycles the system and a first report can take a while at times just loading the site. You can get around this by altering it but I have found making a keep alive service for it works better.
II. RDLC reports are CLIENT CONTAINED reports that are NOT HOSTED ANYWHERE. The extra c in the name means 'Client'. Generally this is an extension of the RDL language meant for use only in Visual Studio Client Applications. It exists in Visual Studio when you add a 'reporting' item.
Benefits of RDLC reports:
You can hookup a wcf service much much much more easier to the dataset.
You have more control over the dataset and can use POCO classes filled with Entity framework objects or ADO.NET directly as well as tables themselves. You can monkey with the data for optimization it before binding it to the report.
You can customize the look more with add on's directly in code behind.
Downsides:
You need to handle parameters on your own and while you can implement wrapper methods to help the legwork is a little more than expected and unfortunate.
The user cannot SEE the parameters in a 'ReportViewer' control unless it is in remote mode and accessing an RLD report. Thus you need to make textboxes, dropdowns, radio buttons on your own outside the control to pass to it. Some people like this added control, I do not personally.
Anything you want to do with servicing the reports for distribution you need to build yourself. Emailing, subscriptions, saving. Sorry you need to build that in .NET or else implement a proxy that already does that from above you could just be getting using hosted reports.
Honestly I like both for different purposes. If I want something to go out to analysts that they use all the time and tweak for graphs, charts, drill downs and exports to Excel I use RDL and just have SSRS's site do all the legwork of handling the email distributions. If I want an application that has a report section and I know that application is its own module with rules and governance I use an RDLC and having the parameters be smaller and be driven by the decisions the user made before getting to the report part of what client they are on and site and then they usually just choose a time frame or type and nothing more. So generally a complex report I would use RDL and for something simple I would use RDLC IMHO.
Q: What is the difference between RDL and RDLC formats?
A: RDL files are created by the SQL
Server 2005 version of Report
Designer. RDLC files are created by
the Visual Studio 2008 version of
Report Designer.
RDL and RDLC formats have the same XML
schema. However, in RDLC files, some
values (such as query text) are
allowed to be empty, which means that
they are not immediately ready to be
published to a Report Server. The
missing values can be entered by
opening the RDLC file using the SQL
Server 2005 version of Report
Designer. (You have to rename .rdlc to
.rdl first.)
RDL files are fully compatible with
the ReportViewer control runtime.
However, RDL files do not contain some
information that the design-time of
the ReportViewer control depends on
for automatically generating
data-binding code. By manually binding
data, RDL files can be used in the
ReportViewer control. New! See also
the RDL Viewer sample program.
Note that the ReportViewer control
does not contain any logic for
connecting to databases or executing
queries. By separating out such logic,
the ReportViewer has been made
compatible with all data sources,
including non-database data sources.
However this means that when an RDL
file is used by the ReportViewer
control, the SQL related information
in the RDL file is simply ignored by
the control. It is the host
application's responsibility to
connect to databases, execute queries
and supply data to the ReportViewer
control in the form of ADO.NET
DataTables.

I have always thought the different between RDL and RDLC is that RDL are used for SQL Server Reporting Services and RDLC are used in Visual Studio for client side reporting. The implemenation and editor are almost identical. RDL stands for Report Defintion Language and RDLC Report Definition Language Client-side.
I hope that helps.
From my experience, if you need high performance (this does depend slightly on your client specs) on large reports, go with rdlc. Additionally, rdlc reports give you a very full range of control over your data, you may be able to save yourself wasted database trips, etc. by using client side reports. On the project I'm currently working on, a critical report requires about 2 minutes to render on the server side, and pretty much takes out whichever reporting server it hits for that time. Switching it to client side rendering, we see performance much closer to 20-40 seconds with no load on the report server and less bandwidth used because only the datasets are being downloaded.
Your mileage may vary, and I find rdlc's add development and maintenance complexity, especially when your report has been designed as a server side report.
Some of these points have been addressed above, but here's my 2-cents for VS2008 environment.
RDL (Remote reports): Much better development experience, more flexibility if you need to use some advanced features like scheduling, ad-hoc reporting, etc...
RDLC (Local reports): Better control over the data before sending it to the report (easier to validate or manipulate the data prior to sending it to the report). Much easier deployment, no need for an instance of Reporting Services.
One HUGE caveat with local reports is a known memory leak that can severely affect performance if your clients will be running numerous large reports. This is supposed to be addressed with the new VS2010 version of the report viewer.
In my case, since we have an instance of Reporting Services available, I develop new reports as RDLs and then convert them to local reports (which is easy) and deploy them as local reports.
If you have a reporting services infrastructure available to you, use it. You will find RDL development to be a bit more pleasant. You can preview the report, easily setup parameters, etc.
While I currently lean toward RDL because it seems more flexible and easier to manage, RDLC has an advantage in that it seems to simplify your licensing. Because RDLC doesn’t need a Reporting Services instance, you won't need a Reporting Services License to use it.
I’m not sure if this still applies with the newer versions of SQL Server, but at one time if you chose to put the SQL Server Database and Reporting Services instances on two separate machines, you were required to have two separate SQL Server licenses:
http://social.msdn.microsoft.com/forums/en-US/sqlgetstarted/thread/82dd5acd-9427-4f64-aea6-511f09aac406/
You can Bing for other similar blogs and posts regarding Reporting Services licensing.
For VS2008, I believe RDL gives you better editing features than RDLC. For example, I can change the Bold on a selected amount of text in a textbox with RDL, while in RDLC it's is not possible.
RDL: abcd efgh ijklmnop
RDLC: abcd efgh ijklmnop -or- abcd efgh ijklmnop (are your only options)
This is because RDLC is using a earlier namespace/formatting from 2005, while RDL is using 2008. This however will change with VS2010
If we have fewer number of reports which are less complex and consumed by asp.net web pages.
It's better to go with rdlc,reason is we can avoid maintaing reports on RS instance.
but we have to fetch the data from DB manually and bind it to rdlc.
Cons:designing rdlc in visual studio is little difficult compared to SSrs designer.
Pro:Maintenance is easy.
while exporting the report from we page,observed that performance gain compared to server side reports.
if you want to use report in asp.net then use .rdl
if you want to use /view in report builder / report server then use .rdlc
just by converting format manually it works
I'm looking to implement SQL Server Reporting Services as our standard reporting platform in our company. We were trialing Crystal Reports, but alas it seems to be plagued by issues.
SQL Server Reporting Services looks to be a great product, but I have a concern or two.
I have some existing web apps in ColdFusion, and the backend is in MySQL. If I move forward with SQL Server Reporting Services, how should I set up my environment? Is there a JDBC connector or is ODBC the only way to talk to this?
How does it integrate for the user? Will I need to re-authenticate the user to view the reports? Will I need to put a link in ColdFusion to link to the Reporting Services system? Is there a way to make it seamless for the user?
Should I port all the backend to SQL Server to fully leverage the SQL Server platform? Should I convert my existing apps to ASP.NET, and make the entire platform SQL Server / ASP.NET?
It's not too bad in the fact that the existing apps / MySQL aren't of a size that is too big to port. So I guess just looking for some best practice advise to see if its okay to use the reporting services component on its own, or if I'm much better to consolidate everything into a Microsoft solution.
I think it'll be easier than you think!
Reporting Services will happily pull reports from any OLEDB or ODBC source, and MySQL has ODBC drivers, so there's no problem getting at your data through an SSRS report.
You can set up the authentication in a number of ways. If your users are already authenticated in your Windows domain, this will be easier:
SSRS needs to know who is viewing the report. It will allow anonymous viewing (if you enable it; it's off by default), but if you're using IE and are logged in to the same domain as the IIS server, it's completely transparent
SSRS can then use this identity to connect to the data source, or it can use another identity. This is configurable per report or per data source.
One thing you could do is embed your reports within iframes in your coldfusion pages. This would make the whole thing seamless. The reports are accessible by sending an appropriately formed URL to the server, so it's quite flexible.
As for changing everything to ASP.NET, you'll really only get benefits from that if you ever need to write (and integrate with) your own code to manage the reporting server, or write custom extensions (data providers, delivery extensions and the like), but in my experience this is so rare as to be not worth considering. Go with what you have for now.
